Girassol is located about 210km north-northwest of Luanda, Angola. It lies in 1,350m of water and has been developed using a subsea facility tied back to an FPSO.
Girassol base-case reserves are around 630 million barrels (bbls) of 32° API crude oil. The field came on-stream in December 2001.
TotalFinaElf E&P Angola is the operator of the $2.8bn project, with a 40% interest. Its partners are Esso Exploration Angola (20% interest), BP (16.7%), Statoil (13.3%) and Norsk Hydro (10%).
The FPSO is designed for two offloading systems, one for normal operation with a buoy and one as back-up offloading, in tandem.
Both systems are located at the bow of the FPSO.
The main offloading system includes a loading buoy, located approximately one mile away from the bow of the FPSO. This can accommodate tankers from 80,000 to 400,000DWT, with a nominal offloading rate of 6,000m³/h through two rigid steel catenary 16in lines.
The tandem offloading is a conventional system with a mooring hawser assembly and handling system, and an offloading hose and its handling system. It is designed to accommodate tankers up to 200,000DWT at a nominal offloading rate of 8000m³/hour.
The FPSO final commissioning was completed and came on-stream in 2001. The average production from Girassol is about 240,000 bpd.
